To all whom it may concern: 1

Be it known that I, HARRY H. BUR'soN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinols, haveinvented certain new and useful Improvements in Studdings for Plaster-Boards or the Like,-of which the following is a specification.

The present invention relates to a studding more especially adapted tosupport la'ste'r boards or analogous substances used 1n the constructionof walls.

The objects of the present invention are,

. to form a simple structure which will be easy of manufacture; tosoconfigurate the structure as to provide a serles of crotches in the bodythereof, in which the ends of the laster board will rest; to providemeans or maintaining the plaster board proper position with respect tothe studdmg pr or to the application of the plaster; to prov de a seriesof openings in the body of the studding to permit 0 the ingress ofplaster to the interior of the studding, whereby the studding istransformed after the apphcation of plaster into a solid structure andto form the ortionsof the studding which lie ing sets of wings 6 and 7.

drawings, the studding is of a shell-like in the b0 y of the wall ofaconfiguration adapted to withstand pressure.

The invention further consists in the features of construction and thecombination of arts hereinafter described and claimed.

Iii the drawings, Figure 1 is a sectional lan view, showin the studdingand plaster card embedded in a completed wall, and showing one means formaintainin the board in place upon the studding PllOI to the applicationof plaster; Fig. 2, a view similar to 'Fig. 1, showing another means formaintaining the plaster boards in'position; Fig. 3, a face view ofthewtudding of the present invention; and' Fig. 4, a perspective of asection of said studding.

The studding comprises a body portion 5, which, as shown, is formed of asingle piece of sheet-metal and is bent into a cross-like configurationto provide op ositelyextend- Ks shown in the nature, whereby a hollowinterior is provided. The wings 6, as shown, extend out from the body ofthe studdin in a direction longitudinally of the plaster Foards, and arei of a substantially rectangular formation in cross section. The wings7, as shown, extend out from the body of the studding in a directiontransversely of the plaster boards and are of a'substantially triangularshape in cross section. This trlangular formation of the wings 7 is forthe purpose of enabling them 'to resist the strain which willnecessarily'be brought to bear thereon, which strain will beproducedbecause these wings, as shown, lie in the body of the wall andthe pressure which is exerted against the faces of the wall istransmitted directly to these wings, and it is a well known mechanicalprinciple that a curved or sloping surface is better adapted towithstand pressure than a fiat one. Were it not for the additionalstrength which is thus given to these walls, these wings 7 mightproperly be formed of a rectangular configuration the same as the wings6. So far as the function of these .wings 7 in maintaining the ends ofthe plas- At the intersection of the wings 6 with the wings 7 are formedcrotches 8, inwhich the ends 9 of plaster boards 10 rest. The crotchesformed at the juncture of the wings would, in the construction shown, befour in number, two of them lying upon either side of the center of thestudding. This provides ameans for placing plaster boards upon oppositssides of the studding, whereby a holow wall construction can be,produced, the wings 6 serving to space the plaster boards apartand-permit of a channel between them.

The wings 7 have a series of cuts along their outer edge, which are of anature 'to form tines 11 along said edge. These tines are adapted to bebent into the position shown in Fig. 1, and when so bent serve as meansfor retaining plaster boards in osition prior to the placing of plasterthemupon. The cutting of the wings 7 to form tirely optional with theuser.

along the edge thereof, through which open- .member being in the natureof a nail or other analogous article. And this member 14 will serve as ameans for securingthe ends of the plaster boards in position when it isnot desirable to bend the tines 11 into position to fulfil this purpose.When the studding is formed with both the holes 13 and the tines 11, theuser may choose which of these means be desires to utilize to performthis work, but, of course, it is evident that the studding may be formedonly with the holes 13, and with the tines 11 eliminated, or vice versa.

In practice the device is used as follows: The studdings are placed atpredetermined intervals at the points where the wall is to be erected.The plaster boards are then inserted in position. This'is accomplishedby simply laying them on top of one another with their ends restingwithin the crotches 8. As they. are placed with their ends in thisposition, then, with the form of studding shown, either the tines 11 arebent into the position shown in Fig. 1 to maintain the boards in properposition with respect to the studding before plaster is applied thereto,or a member 14 is inserted throug the holes 13 to accomplish thisresult, the. manner of securance being en'- After the plaster boardshave been positioned upon the studding, plaster is applied to the outersurface of the boards to form a complete wall, and during suchapplication the plaster will percolate into the interior of the studdingto form the studding into a solidi-- fied mass in place of the originalshell-like structure.

It will be noted that the wings 7 project beyond the outer faces of theplaster board, so that when the plastering is applied it will readilyenter through the openings 12 into the interior of the studding.

- I claim:

1. A studding of the class described, formed of a piece of metal bent toprovide a shell-like structure cross-shaped in section and consisting ofwings, the juncture of the wings providing crotches in which the ends ofthe plaster board rest, one set of wings being rectangular in crosssection, and the other set of wings being triangular in cross section,the rectangular wings being located between the triangular wings, andmeans for securing the ends of the plaster board in place upon thestudding prior to the application of the plaster thereto,

the body of the studdingbeing provided with openings to permit of theingress of plaster thereinto, substantially as described.

2. A studding of the class described, formed of metal bent to provide ashell-like structure cross-shaped in section having oppositely extendingwings, the wings cooperating to provide crotches at their juncture inwhich the ends of the plaster board rest, and tines struck from the bodyportion of one set of wings, ada ted to secure the endsof the plasterboard in position prior to the application of the plaster thereto,substantially as described.
